YOUR Radio - coming soon

Sri Lanka's latest English Language Radio channel part of VIS broadcasting "YOUR Radio" will commence broadcasting soon on 88.3 FM. Presently test transmission of "YOUR Radio" are taking place during the course of the day.

Earlier when I spoke about 94.7 & 88.3, Nik said that no one can operate from colombo on these two frequencies because of technical issues but now Vasantham has moved to 94.7 and VIS opearating on 88.3. If this is so, there are few frequencis open for few operators or channels. they are102Mhz, 101.5Mhz, 105.4Mhz, 104Mhz & 88.7MhzNik, please comments

This is violating the TRC Licensing. Because Islandwide Frequencies (Nuwaraeliya) covers Colombo, if somebody starts on these frequencies there will be interfernce, guardband recommened is 0.3 MHz, here it is 0.2 MHz

Is Vis Will Start There Tv Channel In This Year.Becoz They Have Mention In Newspeaper That Soon They Are Going To Come Up With Tv Channel And Also They Have Mention That They Are Hopping To Start Tv And Radio Channels In Different Languages.

My comment is based on ITU-T recommendations and the regulatory framework of TRC. As per that there should be 300KHz space between two channels otherwise each other will start interfering to other. I.e. 87.6 SLBC and 87.8 Real Radio.

So now 88.3 will have the same issue with very powerful Lakhanda transmission on 88.5

Both TRC and the station owners should take special care when selecting frequencies as it will waste there money as well as disturb the existing channel if not properly planned.

For Nisha,

Frequencies doesnt work like that. 87.5 - 108 MHz the total spectrum available is 206MHz. But the radio frequency allocation done based on Grid and the application which it will be used. For FM radio you need to have 300KHz bandwidth of the allocation. Which mean if you are operating on 88.8MHz, you are already occupying the spectrum from 88.65 - 88.95 MHz as the application it self is frequency modulation and to modulate FM stereo signal you need that much of a spectrum bandwitdh.

So now you know how many channels can be operated on a single GRID, which can be identified as a single coverage area. Now to go on Islandwide, TRC has several Grids on their books and allocation is done based on non-interference base.

Sath FM is lucky to have 103MHz from almost all GRIDs. But as the messy spectrum we have, there is absolutely no other chance to have such single allocation on all grids.

Nik & Kumar,I really agree with the comments you both have expressed becuase these comments include technical classification as well. But in this 88.7Mhz issue, I will give you few examples where these technical regulation violated. Ex 1: 93.3 Mhz SLBC commercial service is operating from Colombo and Lak FM operating from Nuwaraeliya on the same frequency

Ex 2: SLBC National service is operating on this frequency from Nuwaraeliys for years and now Hitz FM is operating on the same frequency from Colombo

Ex 3: 103.5Mhz - SLBC tamil service is operating from Nuwaraeliya for years and now Sath FM is operating on 103.6Mhz from Colombo, Laggala & Gongala(south)

Ex 4: 94.4Mhz: - SLBC City FM is operating from Nuwaraeliya for years and now FM Derana is operating on 94.5Mhz from Colombo.

Ex 5: 100.2Mhz - SLBC english service is operating from Nuwaraeliya for years and now Lak FM is operating on the same frequency from Magalkanda and on 100.1Mhz from Laggala (Matale) & Gongala(south)

these are few practical (not hyphothetical) examples where these regulations and technical aspects are violated openly.

On November 23, CCTV and VIS company of Sri Lanka officially signed CCTV-9 Landing Agreement for jointly broadcasting CCTV-9 through ground-based radio frequency in Colombo, the capital of Sri Lanka, to further expand the coverage of CCTV-9 in South Asia. About 2 million local residents will be able to watch CCTV-9 after its landing in Colombo.

ETHAKOTAWHAT ABOUT THISSinhalese service of CRI to be rebroadcast via SLBCMay 16th, 2009 - 17:34 UTC by Andy Sennitt.China Radio International and the Sri Lanka Broadcasting Corporation (SLBC) have entered into an agreement on broadcasting programmes. This is the result of a discussion between the Information and Media Minister Anura Priyadarshana Yapa and Chinese broadcasting officials. Accordingly, Sinhala programmes of China Radio International will be broadcast through the SLBC. [No further details given].

As Sri Lanka Meny Of Tv Channels Not Clear And No Recieved Tv Transmissions From Colombo, Kandy And Other Sits In to Gampaha District We Request International Tv Network To Come Soon To Srilanka..Because Srilanka Is Now Developed Country..
